FOLDING TOOL.

Application filed January 4, 1926.

To all whom it may concern:

Be it known that I, AARON S. NEWMARK,

a citizen of the United States of America,

residing at city, county, and State of New York, have invented a new anduseful Folding Tool, of which the following is a specification.

My invention relates particularly to handles for implements such assaws, brushes, combs, rulers, fish rods, etc.

The main object is to provide a simple device for securely holding orlooking the parts of a folding handle in the extended position.

Another object is to facilitate the locking and unlocking action.

For these purposes I provide the central section of the handle with twolocking bolts between which is mounted a transmitting gear. One of theseelements is provided with a projecting operating member.

Fig. 1 is a side view showing in dotted lines the handle extended andlocked.

Fig. 2 is an edge view showing the handle folded up.

Fig. 3 is a cross sectional view taken through the central part.

The central section 5 has the two end sections 6 and 7 hinged to it at 8and 9 on 0pposite sides. Reinforcing side plates 10 are preferablprovided and held in place for instance by means of rivets or screws 11.The end sections may likewise be reinforced by side plates 12 and 13held in place suitably for instance by rivets or screws 14 and 15. Thehinge sections may be formed integrally with the side plates.

The locking bolts 16 and 17 are carried by the central section 5 andadapted to be slid back and forth for instance by a projection such as18 or 19 so that they can be housed in the central section or have theirends prO ected into correspondlng recesses Serial No. 79,130.

in the end members. Between the bolts 16 and 17 I mount a transmittingmember 20 which is pivoted on the stud 21 between the side plates. Thisis geared preferably by teeth to the bars 16 and 17 so that when eitherbar 16 or 17 is moved the other moves with it.

The gear 20 may have an external operating knob 22 and in such case theend member 6 may have a recess for the knob 22 when the device is foldedup. Only one projecting operating member however is required.

The device may have a lateral extension 24 or an end extension 25depending upon the character of work to be done by the device.

I claim:

1,. A folding tool comprising a central section, an end section hingedto each end of said central section, a rotatable gear carried by thecentral section, and bolts having teeth meshing with said gear andadapted to engage the end sections when pro-= truded from the centralsection.

2. A folding tool comprising a central section, an end section hinged toeach end of said central section, bolts carried by said central sectionand adapted to engage the end sections, one of said bolts having aprojecting operating member, and a rotatable member carried by thecentral section for transmitting motion from one bolt to the other.

3. A folding tool comprising a central body section, end sections hingedthereto, side plates reinforcing said sections and providing hingemembers, a locking device carried by said central body section andconsisting of bolt members and a transmitting gear member, one of saidmembers having a projecting operator, said plates forming housings forsaid members.
